Exhaust Manifold Pins
This end locating pins are *very* important ~ the reason they're there is : as it goes through normal thermal cycles the exhaust manifold expands and contracts ~ adding bolts on the very ends , often causes the manifold to break .
There's much more engineering in InLine Engines than appears at a glance .
That's why they out last V configuration engines .
